參數

• other
  型別：Microsoft.SqlServer.Types.SqlGeometry
  The SqlGeometry instance to compare to the current SqlGeometry.

傳回值

型別：Microsoft.SqlServer.Types.SqlGeometry
A SqlGeometry object that represents all points in the calling SqlGeometry and the specified SqlGeometry instances that are not present in both instances..

備註

This method always returns nullnull 參考 (在 Visual Basic 中為 Nothing) if the spatial reference IDs (SRIDs) of the SqlGeometry instances do not match.
